Lawyer: Feds investigate Susan Powell case

The lawyer for the family of a missing Utah woman says there's an ongoing federal investigation into Susan Powell's disappearance.

Anne Bremner made the announcement at a Seattle news conference on Tuesday, a day after local officials in Utah said they had closed their investigation into the Susan Powell case.

Newly released police records show that Utah officials believe Josh Powell likely killed his wife and that his brother, Michael Powell, helped dispose of the body, but authorities felt they didn't have enough evidence to prove that theory in court. Both Josh Powell and Michael Powell committed suicide.
